Figure 44. Internal VCO and Clock Distribution
Internal VCO and Clock Distribution
When using the internal VCO and PLL, the VCO divider must
be employed to ensure that the frequency presented to the channel
dividers does not exceed their specified maximum frequency of
1600 MHz (see Table 3). The internal PLL uses an external loop
filter to set the loop bandwidth. The external loop filter is also
crucial to the loop stability.
When using the internal VCO, it is necessary to calibrate the
VCO (Register 0x018[0]) to ensure optimal performance.
For internal VCO and clock distribution applications, use the
register settings that are shown in Table 24.
Table 24. Settings When Using Internal VCO
Register
Function
0x010[1:0] = 00b
PLL normal operation (PLL on).
0x010 to 0x01D
PLL settings. Select and enable a reference
input; set R, N (P, A, B), PFD polarity, and ICP
according to the intended loop configuration.
0x018[0] = 0b,
0x232[0] = 1b
Reset VCO calibration. This is not required
the first time after power-up, but it must be
performed subsequently.
0x1E0[2:0]
Set VCO divider to divide-by-2, divide-by-3,
divide-by-4, divide-by-5, and divide-by-6.
0x1E1[0] = 0b
Use the VCO divider as the source for the
distribution section.
0x1E1[1] = 1b
Select VCO as the source.
0x018[0] = 1b,
0x232[0] = 1b
Initiate VCO calibration.
